Grid vs Flexbox
The Architect’s Jam
Section titled “The Architect’s Jam”Flexbox and Grid are not rivals.
They’re specialists.
- Flexbox: one-dimensional flow (row or column)
- Grid: two-dimensional layout (rows and columns)
If you pick the right tool, your CSS gets smaller.
If you pick the wrong one, you start wrestling the browser… and losing.
